1.5. Connectors - Video-Interface
The video-interface converts the video signals of connected after-market sources in a factory
monitor compatible picture signal which is inserted in the factory monitor, by using separate
trigger options. Further it reads the vehicle’s digital signals out of the vehicle’s CAN-bus and
converts them for the video interface.
1.6. Settings of the 8 Dip switches (black)
Some settings have to be selected by the 8 dip-switches at the
video-interface. Dip position down is ON and position up is OFF.
See the following chapters for detailed information.

2. Installation
Switch off the ignition and disconnect the vehicle’s battery! The interface needs a
permanent 12V source. If -according to factory rules- a disconnection of the battery has to
be avoided, it should be sufficient to use the vehicle’s sleep-mode. In case, the sleep-mode
doesn’t succeed, the battery has to be disconnected with a resistor lead.
The connection’s power has to be checked for being start-up proven and permanent.
Before the final installation, we recommend a test-run of the interface. Due to changes in
the production of the vehicle manufacturer, there’s always the possibility of
incompatibility.
2.1. Place of installation –video-interface
The video-interface is performed to be installed at the head unit’s rear side.
Erfahrungswerte zu Einbauorten:
Radio/Navi in Peugeot 2008 FY 2019 vehicles: Directly behind the display.
Head Units in Peugeot 5008 and Opel Grandland X vehicles: Behind the centre console (for
this, remove the panel in the passenger footwell).

2.5.1. Audio insertion
This interface can only insert video signals into the factory infotainment. If an AV source is
connected, the audio insertion has to be performed by a factory aux input or an FM
modulator. The inserted video-signal can be activated simultaneously to each audio-mode of
the factory infotainment.
If 2 AV-sources shall be connected to the infotainment, for audio switching an additional
electronic part is required.
2.5.2. After-market front camera
The red power supply output ACC/front cam out 12V (max 3A) can be used to power
a front camera. If Dip 1 is set to ON (of the black 8 dips), the power supply output
supplies +12V (max 3A) when the reverse gear is engaged and additionally
10 seconds delay after reverse gear is disengaged.
Note: In addition, a manual switch-over to the front camera input is possible via keypad
(short press) from any image mode. The power supply output supplies +12V then, too (if Dip
1 is set to ON and the front camera input is selected).

Version 11.08.2021 HW: CAM(V100)/(V52) RL4-NAC08
Page18
2.5.3. After-market rear-view camera
Some vehicles have a different reverse gear code on the CAN-bus which the video-interface
is not compatible with. Therefore, there are two different ways of installation. If the video
interface receives a signal of the reverse gear, the green wire “Reverse-OUT” of the 20pin
cable should carry +12V while the reverse gear is engaged.
Note: Do not forget to set dip5 of the video-interface to ON before testing.
2.5.3.1. Case 1: Video interface receives the reverse gear signal
If the CAN-bus interface receives +12V on the green wire of the 20pin cable when reverse
gear is engaged, it will automatically be switched to the rear-view camera input “Camera IN”
while reverse gear is engaged.
The 12 V power supply for the rear-view camera (max 3A) has to be taken from the
green wire of the 20pin cable to avoid an unnecessary, permanent power supply to
the camera electronic.
For the operation, both green cables “Reverse IN” and “Reverse OUT” have to remain
connected.

Version 11.08.2021 HW: CAM(V100)/(V52) RL4-NAC08
Page19
2.5.3.2. Case 2: Video interface does not receive the reverse gear signal
If the video interface does not receive +12V on the green wire of the 20pin cable when
reverse gear is engaged (not all vehicles are compatible), an external switching signal from
the reverse gear light is required. As the reverse gear light’s power supply isn’t voltage-
stable all the time, an ordinary open relay (e.g AC-RW-1230 with wiring AC-RS5) or filter (e.g.
AC-PNF-RVC) is required. The diagram below shows the connection type of the relay.
Disconnect the green cable’s pre-connected male- and female connectors of the
20pin cable and connect the green input cable “Reverse-IN” to the output connector
(87) of the relay.
Note: Not least to avoid short circuits, the best solution should be, to crimp a male
4mm connector to the relay’s output cable and connect it to the green cable’s female
4mm connector. The output-cable “Reverse-OUT” remains disconnected as it’s out of
function.
Connect the Reverse light’s power-cable to coil (85) and the vehicle’s ground to coil
(86) of the relay.
Connect the output connector (87) of the relay to the rear-view camera’s power-
cable, like you did it to the green “Reverse-IN” cable before.
Connect permanent power / 12V to the relay’s input connector (30).

Version 11.08.2021 HW: CAM(V100)/(V52) RL4-NAC08

2.6. Connection - external keypad
Connect the keypad’s female 4pin connector to the video-interface’s male 4pin
connector.
Note: Even if the switching through several video sources by the keypad mightn’t be
required, the invisible connection and availability is strongly recommended.
